I've had two ferral hogs come in to a cotton tail rabbit tape, one 250 pound boar gave me a good scare. When he got to 20 yards I stood up and told him it was a trick, but he kept right on comming to around ten yards where he pulled up and we had a stare down for a few seconds. He never did get scared, just turned and left. I, on the other hand, was just a little pumped. One more second and he would have been bleeding from many holes!
